Oxygen and oxyfuel combustion systems play a key role in iron production in both cupola and rotary furnaces. Oxygen enrichment or oxygen lancing in cupola furnaces leads to increased productivity and flexibility as well as reduced coke rates combined with blast air and off-gas reductions. In rotary furnaces, oxyfuel is sometimes the only way to produce iron economically.
Safe and efficient transfer of liquid iron from the melt shop to the casting line is important to achieve high-quality casting products. Properly conditioned iron in well heated transfer ladles plays an important role in achieving this target. Oxyfuel-heated ladles are an efficient and effective way of maintaining transfer heat.
